A.
1. The cost for bike rental is the number of customers · $30. So it is the number of customers times 30.
C=30·n
2. The cost for food and camp costs is the number of customers · $125. So it is the number of customers times 125.
C=125·n
3. The cost for van rental is the number of customers · $700. So it it the number of customers times 700.
C=700·n
B. TC= bike rental costs + food and camp costs + van rental costs.
C. P= income - total cost.
So the profit is the income minus the total cost.
